[n5=Dxdiag Report]You can generate a text or XML formatted DirectX Kernel Diagnostics report, which I find easier to read than the individual screens.  I also use it for troubleshooting and informational purposes.  It does contain a lot of helpful information like driver names, driver dates, hardware IDs, etc. . .
